WINDOW FASTENER.

This ,invention relates to an improved article of hardware which may beconven- .iently and specifically designated as a window sash holder orfastener. I x The invention has more specific reference to a device ofthis kind which is mount ed upon the top of a lower slidingsash and iscooper-able with the lower portion of the upper sliding sash forpreventlng unauthorized opening of the sashes from the outside of thewindow.

The details of the structure and their relative arrangement andassociation will become apparent from the following description anddrawings.

in the accompanying drawings forming a part of this application, and inwhich like numerals are employed to designate like parts throughout thesame:

Fig. 1 is a fragmentary vlew of a portion of a window showing theimproved sash holder in operative position.

Fig. 2 is an enlarged side view in section and elevation showing thespecific construction of the holder more plainly.

In carrying out the invention, I employ a mounting bracket 1 which inthe present instance comprises an attaching base 2 having upstandingears 3 through which a pivot pin or bolt 4 extends.

Pivotally mounted upon the bolt 4 is the improved retainer generallyindicated by the reference character 5. This retainer comprises asubstantially U-shaped member having a short arm 6 pivoted upon the pin4: and a long arm 7 extending outwardly beyond the window frame asshown.

The intermediate portion or bight of the U-shaped member is in the formof an arcuate plate 8 carrying a corrugated rubber facing 9. Attached tothe free end of'the arm 7 is a depending operating chain 10 having afinger piece 11 at its bottom. in addition,

a curvilinear or bowed spring 12 is fastened at one end to the baseportion 2 of the attaching bracket and has its free end portionoverhanging and bearing upon the arm 6 at a point spaced from the pivotconnection of the same.

Under normal conditions, the spring 12 serves to yieldably hold facing 9in locking contact with one of the side rails of the upper sash 13 whenthe bracket 1 is fastened upon the top of the lower sash 14 as shown.Because of the peculiar shape and location of the device, it is obviousthat when thus positioned, it is impossible to .push the upper sash 13down or to lift the lower sash 14 up. It is obvious, though, that if theupper sash has been lowered somewhat and it is desired to raise andclose it, this can be done without interference of the locking device."This isalso true of the I lower sash; that is, if it has been raisedslightly it can be lowered to closed position Without interference ofthe device. It is also obvious that the operator may, at any time, pullupon the operating chain 10 to temporarily hold the device out ofoperation when the sash is to be raised or lowered as may be desired.

With the device shut, however, considerable difliculty would beexperienced in attempting to open the sashes from the interior. It isalso evident from the foregoing description that I have evolved and proI duced a comparatively simple and inexpensive lock that can be ut inplace by unskilled hands. Although it inds severel ,it nevcrthe}llessdoes not mar or destroy t e Window sas The tighter the push against thesashes, the tighter'the device binds. The device is not unsightly in'any instance and has proven to be successful in operation afterconsiderable actualnse.

The foregoing and other features and advantages of the invention havedoubtless been made appai'ent by the description and drawings. Moreoverthe description will suffice, when taken in connection with thedrawings, to enable persons skilled in the art to obtain aclear'understandin of the inven tion. Therefore a more lengt mydescription is thought unnecessary,

While the preferred embodiment of the in vention has been shown anddesfi'ibed, it is to be understood that minor changes coming within thefield of claimed invention may be resorted to if desired.

Having thus described my invention, What I claim as new is The hereindescribed sash fastener comprisin a bracket, a vertically swingable U-shape retainer having an arcuate toothed bight portion adapted for usein opposed re lation to a window sash and also having at the lower endofsaid arcuate lower arm pivoted at its en remote from the arcuate portionto the said bracket, and

ortion a short further having a long arm extending in the same verticalplane as the lower arm from the upper end of the arcuate portion andoverhanging and spaced from the lower arm and the bracket and extendingbeyond the pivoted end of the lower arm and the bracket, a string orcable connected to and directly pendent from the end of the long arm,and a bowed spring attached to the bracket below the pivot connectionof-ihe lower arm of the retainer and extending upwardly from the pointof connection and,

outwardly beyond the pivot connection of the lower arm and having a freeend portion overhanging the pivot connection and the adjacent portion ofthe lower arm of the retainer and exerting a downward pressureon saidlower arm; -said free end portion of thespring resting in the spacebetween the lower and upper arm, whereby it is protect- 20 ed by theupper arm.

In testimony whereof I- afiix my signature.

WILLIAM E. MORRISON.
